Problems solved by technology

The disadvantages of this method are: poor real-time performance (the polling cycle depends on the number of protected files and the number of bytes), poor security (there is an unsafe period in the polling cycle), and high system load
This file protection method has two characteristics: one is that the protection function occurs after the file is damaged, and there is a recovery process; the other is that the protection depends on the backup file

Embodiment Construction

[0030] The technical solution will be further explained and illustrated below with non-limiting examples.

[0031] A file protection technology based on Windows system file filter driver, the operation process is as follows: figure 1 Shown:

[0032] Start at step 101: load the driver, and load the driver file by calling the Service management API provided by the Windows system; the driver is written according to the Windows driver development specification for processing file access requests.

[0033] Start step 102 then: set up and maintain protected file set, obtain protected file set information after being used for step 101 driver loading; File set is described by following several attributes: protected directory list, (under protected directory) List of subdirectories excluded from protection, (under the protected directory) list of file names excluded from protection, (under the protected directory) file types excluded from protection (support name fuzzy matching and wi...

Abstract

The invention belongs to InforGuard web page tamper-proof system middleware field, particularly is a file protection technology based on Window system file filter drive, which is realized by the following steps: A: loading drive, by calling Service provided by Window system to manage API in order to load a drive file; B: building up and maintaining a protected file assembling to obtain protected file assembling information after loading drive; C: building up and maintaining a privilege progress list to obtain privilege progress information which can visit the protected file after loading the drive; D: processing a file visit request to realize file protection according to claim. The scheme changes previous process ideas of file protection technology, and replaces passive prosthesis with active interception so that invalid act of amending is directly forbidden.

Description

technical field [0001] The invention belongs to the field of file protection under the Windows environment, in particular to a file protection technology based on the Windows system file filter drive. Background technique [0002] In the Windows system, there is a need to protect specified files, especially some resource files accessed through the network. The so-called protection is to prevent files from being accessed by unauthorized visitors, including reading file content, modifying file content, naming files, deleting files, modifying fixed attributes of files, creating new files in protected directories, and so on. [0003] At present, there are many file protection technologies based on the Windows system. A brief analysis is as follows: [0004] 1. Polling check mechanism [0005] The method is to check the content of each protected file one by one by traversing the disk files, and restore the file content when it is found that the file content has been illegally m...
